Ok, use your imagination because I did that in 1 minute (and my registration marks aren't perfectly spaced).
The red dots on the sides are the registration marks (remember they should be ON the sewing line - inside the seam allowance, not edge of fabric)
You can do the math, or divide it by folding and marking the middle, then the quarter, etc.
If you have the same amount of marks on the side as the bottom, you'll end up with a diamond shaped crosshatch - and who cares what the exact degree measurement is.
Of course, straight horizontal and vertical lines would works also. ;-)
or just play around

Hope that helps.
